The <u>subject </u>line for any e-mail messages you write should clearly state the intention of the e-mail.
Electronic mail (e-mail) is a method of digital communications in which messages are exchanged through the internet. The messages are sent from a sender to one or more receivers. Depending on user’s perspective, every user uses e-mail differently. Communicating via e-mail requires e-mail platforms such as G*mail, Ya*hoo! Mail, Hot*mail, and Out*look etc. In the every e-mail, there is a subject line that clearly state the intention of the e-mail.
Subject line is an important element of an e-mail. Through the subject line, the message written in the e-mail is briefly summarized in six to eight words. A clearly written subject line provides the recipient a clear understanding that why the email has been sent. When recipient replies back to the e-mail, the subject line is changed accordingly.
This is the subject line of the e-mail that convince the receiver whether to open and read the e-mail. So, it should be written in the way that gives clear intention of the e-mail. We can say that the subject line of the e-mail is the most significant few words in the whole e-mail to convey the main purpose of the e-mail.
